ConstructionThe GEMÜ R690 diaphragm valve has a low maintenance membrane actuator which can be controlled by air or inert gases. Normally Closed (NC), Normally Open (NO) and Double Acting (DA) control functions are available. All medium wetted parts and the actuator housing are made of high-grade plastic materials which can be selected to suit the application.

Features• Suitable for inert and corrosive* liquid and gaseous media• Insensitive to particulate media• Optional flow direction and mounting position• Nominal pressure PN 10 / 150 PSI• Nominal size DN 15 - DN 100 / NPS 1/2” - NPS 4”• Actuator housing in glass fibre reinforced PP• Valve body and diaphragm available in various materials and designs

Advantages• Compact, lightweight construction and high performance• Good flow characteristics due to flow optimized valve body• Proven long-life membrane actuator• Leak detection hole• Diaphragm easy to replace• Adjusted instrumentation• Optical position indicator as standard• Optional accessories

- Electrical position indicator with microswitches or proximity switches - Positioner and process controller - Stroke limiter - Pilot valve

The Kv values for other product configurations (e.g. other diaphragm or body materials) may differ. In general, all diaphragms are subject to the influences of pressure, temperature, the process and their tightening torques. Therefore the Kv values may exceed the tolerance limits of the standard. The Kv value curve (Kv value dependent on valve stroke) can vary depending on the diaphragm material and duration of use.

The control pressure depending on the prevailing operating pressure, as shown in the diagram, is intended as a guide for operating the system with low wear on the diaphragm.
